Everything else will be the same. As the flashbacks become more common, they can become frustrating, even overwhelming. People who experience visual disturbances caused by HPPD often experience one or more of the following symptoms:. It is still unclear whether these symptoms are directly caused by the disorder.

Researchers and doctors do not yet have a solid understanding of who develops HPPD and why. However, it can arise in anyone, even after a single exposure to triggering drugs. In some cases, people experience HPPD after their very first use of a drug. Other people use these drugs for many years before experiencing symptoms. Any and all hallucinogenic episodes are of concern.
This is especially true if you experience these episodes frequently. The doctor may perform an examination, obtain laboratory tests, and take an image of your brain. They are not going to judge your previous or recent drug use. If the doctor performs a medical evaluation and the testing and imaging results are clear, they may recommend a psychiatric examination. If a psychiatric evaluation does not fit with other more common diagnoses, HPPD may be the resulting diagnosis.
Reaching an HPPD diagnosis may be easier if your doctor is familiar with the condition and your past drug use. If your doctor suspects another possible cause, such as side effects of a medication, they may request blood tests or imaging tests. These tests can help them eliminate other possible causes of your symptoms. If other tests come back negative, an HPPD diagnosis is likely. These factors will help your doctor reach a diagnosis and help you avoid possible complications from drug interactions.
If you feel your doctor is not treating you properly or taking your symptoms seriously, find a doctor who makes you comfortable. HPPD has no recognized medical treatment. Since so little is known about the development of HPPD, it can be difficult to find a psychiatrist with experience treating it. Symptomatology may be accompanied by depersonalization, derealization, anxiety, and depression.
But researchers have proposed explanations. One centers on memory. The basic idea is that LSD somehow changes the way the brain interprets visual stimuli.

Here are some of the responses:. IBeatMyGlied wrote:. The realization that this is not going to go away soured the whole experience tho.
I kept taking drugs simply because I was addicted and felt like life is no fun without them. My HPPD got gradually worse over time and more symptoms appeared. First, I noticed mild tracers, which got worse over time again due to continued drug use and then tinnitus and brain fog. But primarily my symptoms are visual. Halven89 wrote:. I also see halos from light sources.
Although my HPPD is quite pronounced, I have learned to accept it and almost only notice it when I pay attention to it. There is a massive distinction between those two things. Flashbacks that continue to occur after the original drug effects have worn off are a medically recognized phenomenon, which is documented in the Diagnostic and Statistical Manual of Mental Disorders DSM-5 as hallucinogen persisting perception disorder flashbacks.
A drug-related flashback is the sensation of re-experiencing the effects of a drug after the true effects of the drug have worn off. Most often, this type of flashback is associated with the re-experiencing of the effects of a hallucinogenic drug such as LSD "acid" or magic mushrooms.
Flashbacks typically happen in the days or weeks following ingestion of the drug but can happen months or even years after the drug use has been discontinued. Flashbacks are not usually as intense or long-lasting as an actual drug experience, usually lasting just seconds or minutes, and are easier to control mentally than intoxication or a bad trip. Symptoms of hallucinogen persisting perception disorder HPPD include:.
Occasionally, people or situations may seem bizarre or ridiculous, or the person experiencing the flashback may feel dissociated.
When this happens in a social situation requiring self-control, it can be embarrassing or scary for the person experiencing it.
The following co-occurring mental illnesses are also common in people with HPPD but not required to make a diagnosis:. If you or someone you care about is experiencing intense and frequent flashbacks, you should visit your healthcare provider. It's important to be honest about your current and past drug use, as well as any history of mental illness.
Remember, the doctor is not there to judge you but to help you find the right treatment to ease your symptoms. Flashbacks can come on unpredictably or in response to a trigger, such as tiredness, anxiety, or stress. Triggered flashbacks can be especially difficult as the person may already be feeling vulnerable due to the trigger, which can make the out-of-control feeling of the flashback all the more confusing and upsetting.
The experience of a flashback can also be self-induced by the person thinking about the experience of tripping on a hallucinogenic drug. While we don't know a lot about what causes HPPD, we do know what doesn't cause them, including the following:.
The only certain cause of HPPD is previous hallucinogen use. You cannot have HPPD if you've never used a hallucinogenic drug. In some cases, flashbacks are caused by an underlying physical condition such as migraines, brain lesions, or a seizure disorder.
Specific disturbances in one or more senses sight, hearing, taste, smell, and touch can be brought on by eye conditions, neurological diseases, hearing problems, and stroke. If you are experiencing hallucinations, getting a timely and accurate diagnosis is crucial.
While most of the physical and mental health conditions that can cause hallucinations, including drug use can be managed or treated, some can have serious consequences if left untreated.
People who experience flashbacks may feel a great deal of distress and even fear that they are losing touch with reality. However, it's important to know that many of the conditions that can cause these visual disturbances—including drug use—are treatable. If you are experiencing flashbacks, whether or not you have taken LSD or another drug, talk to your doctor.
These professionals can figure out what is causing your flashbacks, prescribe the appropriate treatment, and make sure you have access to resources, support, and tools to help you cope. Learn the best ways to manage stress and negativity in your life.
